SKF YAT 208 Insert Ball Bearing

Industrial Use & Application

The SKF YAT 208 insert ball bearing is a robust, pre-assembled bearing solution engineered for demanding industrial applications where reliable performance and high durability are paramount. With dimensions of inner diameter 40 mm, outer diameter 80 mm and width 36 mm, this component integrates seamlessly into standard bearing housings or acts as part of a full bearing unit offering efficient mounting and service-friendly replacement.
By design it simplifies the assembly process with its set-screw locking mechanism, enabling quick fit-in and replacement - a key advantage in high-throughput or production-critical environments. Its structure supports radial loads and moderate axial loads, making it suitable for drives, conveyors, gears, agricultural machinery and other systems where downtime must be minimized.

Key Benefits & Technical Features

• Optimised dimensions (40 x 80 x 36 mm) - clear standard sizing allows straightforward integration into existing machinery and control of spare-parts inventory.

• Insert ball bearing construction - based on classic ball bearing technology, offering smoother operation, lower friction and stable rotation compared with some heavy-duty roller types.

• High durability - manufactured to withstand challenging operational conditions including vibration, load variation and fluctuating speeds, supporting durability and reduced maintenance.

• Simple locking method - the set-screw lock permits fast, secure fitting on a shaft, reducing downtime and effort in maintenance operations.

• Compatibility with bearing housings and units - ideal for OEMs and maintenance departments implementing modular systems or retrofitting via a bearing unit in a machine's design.

By selecting this insert bearing, B2B buyers gain a dependable component that aligns with maintenance strategies focused on uptime, simplified logistics and predictable lifecycle management.

Technical Specifications & Selection Guidance

• Type: Insert ball bearing (pre-assembled)

• Model: SKF YAT 208

• Dimensions: d = 40 mm, D = 80 mm, B = 36 mm

• Construction: Ball bearing technology with locking ring/ set screw on inner ring

• Load ratings: dynamic load rating approx. 30.7 kN, static load rating approx. 19 kN

• Speed limit: typical maximum around 4 800 rpm (depending on installation and lubrication)

• Mounting recommendations: Ensure correct shaft diameter (40 mm), confirm the housing inner diameter for outer ring (80 mm), check that width (36 mm) accommodates the assembly. Use correct lubrication and ensure set-screw locking is tightened per specification.

• Integration context: Works effectively within a bearing housing or as part of a modular bearing unit, making it suitable for industrial machine builders, OEM supply and maintenance operations.

Selecting the proper insert bearing helps ensure components such as conveyors, mixers, agricultural equipment or fans run smoothly with fewer stoppages, maintained alignment and predictable service intervals.

FAQ

Q1: What distinguishes this insert bearing from a standard ball bearing?
A1: The SKF YAT 208 is an insert ball bearing designed for fast assembly within housings or units. Unlike a simple shaft łożysko kulkowe (ball bearing), it comes pre-assembled with a locking mechanism, facilitating simpler installation in industrial applications.

Q2: Can this bearing be used in a bearing housing or as a bearing unit?
A2: Yes. Thanks to its standard sizing and insert form, it integrates nicely into an obudowa łożyskowa (bearing housing) or as part of a ready-to-install jednostka łożyskowa (bearing unit). This makes it an excellent choice for retrofits and B2B supply chains.

Q3: What types of applications are suitable for the YAT 208?
A3: It is commonly used in industrial drives, conveyor systems, agitation equipment, agricultural machines, packaging lines and other aplikacje przemysłowe where compact design, speedy installation and high reliability are required.

Q4: How important is the set-screw lock in this unit?
A4: The set-screw locking mechanism allows secure fixation on the shaft without requiring additional adapter sleeves, speeding up maintenance and ensuring alignment and stability - valuable for reducing downtime.

Q5: What maintenance requirements apply to this bearing?
A5: The bearing is pre-lubricated and sealed for standard duty, but in heavy industrial environments regular checks of lubrication condition and alignment are beneficial. Use in harsh conditions may warrant periodic inspection to ensure continued wysoka trwałość.
